SAFETY DEVICE OR SAW-GUARD.

Specification of Letters Patent.

Application filed. November 16, 1907. Serial No. 402,390.

To all whom it may concern:

Be it known that I, GEORGE SCHUBERT, a citizen of the United States,residing at Fort Worth, in the county of Tarrant and State of Texas,have invented a new and useful Safety Device or Saw-Guard for Saws andSimilar Cutting-Tool Operatives, of which the following is aspecification.

My invention relates to a safety device for operatives of saws andsimilar cutting tools and consists of a spring or springs arranged torest on the timber in frontof the saw and whip or press down on to theoperatives fingers as the end of the timber nears the saw and therebyarrest said fingers or hand, or prevent them being engaged by the saw bymistake; and second, to arrange brackets on each side of the saw toavoid the timber raising and engaging the top of the saw.

In the drawings, Figure 1 shows a portion of a band saw provided with myinvention, and Fig. 2 is a top plan view of same. Fig. 3 shows theinvention as applied to a circular saw, showing both ends of the springelevated by the timber. Fig. 4 is a similar view, with the timberomitted, and showing the springs in their normal position, and Fig. 5 isa top plan view of same.

Referring to Figs. 1 and 2; 1 represents a portion of the blade of aband-saw extending over a wheel above, (not shown,) and over a wheel 2on a shaft 3 supported by the column i 4, 5 is the table supported by abracket 6 secured to the column4. All arranged as in common use. 7represents a slot formed in the column 4 a short distance above thetable 5. 8 is a bracket secured adjustably in said slot 7 and extendingto near the rear edge of the saw, and having said end perforated toreceive a bolt 9. 10 is a s ring coiled on the bolt 9 on each side ofthe racket 8 and projecting with its body'12 rearward, said end can beunited as seen in Fig. 2 or separated as seen in Fig. 5. The forwardends of said spring extend beyond the teeth of the saw and are bentdownward as at 13. The body of said spring is provided with severalcoils 14 and 15 to give it the desired elasticity. The coils 14 areturned inward and on each side of the blade of the saw to form a guideand prevent the ends of the spring from engaging the teeth of the saw.The rear ends of the springs are longer or heavier than the front ends,to cause said spring to move to the position seen in Fig. 4 after thetimber is removed.

Figs. 3, 4 and 5 show the invention in use on a circular saw, 16 beingthe table supported by corner posts 17 17 braced by side bars 18. 19 isa saw operated in said frame, as in common use. 20 represents an armsecured to one-of the side boards 18 and projecting towards the saw, andwith its end 21 turned forward. 22 22 are slotted brackets securedadjustably on the end 21, one on each side of the saw. 23 23 are stripssecured on the lower end of the brackets 22 22 and formed of amplelength to protect the teeth of the saw above the timber. The springs 10are coiled or pivoted on the bolt 29 and constructed as above described.

As the timber 24 is fed to the saw it will raise the rear end of thespring and thereby press the front end down on the timber; and as thelast end of the timber nears the saw it will passbeyond the front end ofthe springs and cause-said ends to Whip or spring down on to theoperators fingers or hand and prevent it being carelessly shifted in tothe saw. The brackets with the springs are adjusted to accommodate thestandard thickness of the timber; and the front ends of the springs areof a length to extend to near the table after leaving the timber. Thestrips 23 23 in connection with the springs will prevent the timber fromraising and reaching the top of the saw and shootingacross the plant todeal death and destruction.

Having described my invention; what I claim is 1. In a saw guard, asupport extending over the saw, a spring pivoted on the support andhaving an end projecting behind the blade of the saw and having aforward end bent downward.

2. In a saw guard, a support extending over the saw, a spring pivoted onthe sup ort and having an end projecting in front 0 the saw and bentdownward and said spring having a heavier end projecting behind theblade of the saw to partly raise the forward 1 gaged by the material tobe sawed to increase end of the spring. the tension or pressure of thespring.

3. In a saw guard, a support extendin '1! over the saw, a spring pivotedon the support GEORGE SOHUBEh 5 and having an end projecting in front ofthe Witnesses:
